Called them today and they had the Shipping center pull one and inspect it for me :
The Parts Geek Ad turns out to be a Old Stock ( I expect ) Pump with Metal Impeller
so worthless for my Needs .
However REBUILT : the Porsche Factory MAKE"S THIS Pump with Factory Warranty ( 2 Years ) has a Plastic Impeller however is best to request Plastic as they still have a few metal one's come through sometimes. Price $189.89 part number 928-106-915-AX ask for Sean in parts 1 888 502 5927 if interested . BTW : No Affiliate here . That's a Porsche Dealer and the Part comes right from the Porsche Factory .
Also Has the " New Porsche Pumps" Brand New $648 ( same as rebuilt as far as all the Parts inside ) However the casting of the Pump is brand New . All else is the same inside
Same bearing / Impeller / seal and such as I understand it . Now perhaps I am wrong but that's why the Numbers are here so you can ask for yourself if interested
Link to new water pump or look it up
Note the Reman units for $189.89 are not listed you must ask for them

Happy New Year
